Abstract
This paper reports an inquiry into approaches to grapbing required in Physics and
Applicable Mathematics tertiary entrance examinations (TEE), in Western Australia. The
focus in the paper is on the different graphing practices in Physics and Applicable
Mathematics in relation to gradient and transformed data, and in regard to use of graphics
calculators. The differences mediate against transfer between the subjects and are one
explanation for students' poor performance in graphing in the Physics TEE.
